PLEASE RECOGNISE THE IC NUMBER.

I have a remote controlled one celling fan speed controlled + one light on/off circuit. The circuit is consist with one 8 pin IC, one optocuplor, one relay, one BT 134 and one 547 transistor, and few resistance and capacito. It is very simple circuit without using microcontroller, so I want to make this circuit which will be cheap for me and my frieds. But there is a problem with the circuit that is the IC number is erase from the Parts, So, I request that if any one able to get some idea of the IC is possible. PIN 1-is supply voltage(+), PIN 2- to Sensor, PIN 3 & 4-Triggering (to two micro switch), PIN 5-Output Pulse, PIN 6-Output DC, PIN 7-Relay & middle leg of BT-134, PIN 8-GND.
The above is something little about the circuit IC, is it possible to identify the IC number from the above Pin description? if possible, please infromed me.
